Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-E3 SUMO-protein ligase PIAS4/PIASy antibody (AB58416)

IHC image of ab58416 staining in human testis formalin fixed paraffin embedded tissue section, performed on a Leica Bond^TM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab58416, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

补充信息

This supplementary information is collated from multiple sources and compiled automatically.

The E3 SUMO-protein ligase PIAS4 also known as PIASy functions as an E3-type small ubiquitin-like modifier (SUMO) ligase. This protein plays a role in SUMOylation a post-translational modification process where it catalyzes the transfer of SUMO from E2 conjugating enzyme to target substrates. PIAS4 has a mass of approximately 57 kDa and is expressed in various tissues including the brain heart and skeletal muscle. It shows localization in the nucleus reflecting its role in regulating nuclear processes.

Biological function summary

This protein modulates transcription by interacting with and modifying transcription factors through SUMOylation affecting their stability and activity. PIAS4 participates in multiprotein complexes which can influence gene expression and cellular responses to stress. Its role in DNA repair processes is significant as it SUMOylates proteins involved in homologous recombination and DNA damage response pathways aiding in maintaining genomic integrity.

Pathways

PIAS4 plays a role in the regulation of DNA damage repair and the STAT signaling pathway. It cooperates with proteins like BRCA1 and RAD51 in DNA repair ensuring the correct repair of double-strand breaks. In the STAT signaling pathway PIAS4 influences STAT transcription factors impacting various cellular activities including growth and apoptosis. This modulation links PIAS4 to cellular responses relevant to growth and stress.

PIAS4 has connections to cancer and neurodegenerative diseases. Mutations or altered expression of PIAS4 can disrupt DNA repair processes leading to an increased susceptibility to cancer due to accumulated genomic instability. PIAS4 also interacts with proteins like p53 in pathways associated with cancer development. Additionally its involvement in stress response mechanisms could link it to neurodegenerative diseases possibly through affecting neuronal cell survival and function.

靶点信息

Functions as an E3-type small ubiquitin-like modifier (SUMO) ligase, stabilizing the interaction between UBE2I and the substrate, and as a SUMO-tethering factor (PubMed : 12511558, PubMed : 12631292, PubMed : 12727872, PubMed : 15831457, PubMed : 15976810, PubMed : 22508508, PubMed : 32832608). Mediates sumoylation of ALKBH5, AXIN1, CEBPA, KLF8, GATA2, PARK7, HERC2, MYB, TCF4 and RNF168 (PubMed : 12223491, PubMed : 12511558, PubMed : 12631292, PubMed : 12727872, PubMed : 12750312, PubMed : 15831457, PubMed : 15976810, PubMed : 16617055, PubMed : 22508508, PubMed : 34048572). Plays a crucial role as a transcriptional coregulation in various cellular pathways, including the STAT pathway, the p53/TP53 pathway, the Wnt pathway and the steroid hormone signaling pathway (PubMed : 11388671). Involved in gene silencing (PubMed : 11248056). In Wnt signaling, represses LEF1 and enhances TCF4 transcriptional activities through promoting their sumoylations (PubMed : 12727872, PubMed : 15831457). Enhances the sumoylation of MTA1 and may participate in its paralog-selective sumoylation (PubMed : 21965678). Binds to AT-rich DNA sequences, known as matrix or scaffold attachment regions (MARs/SARs) (By similarity). Catalyzes conjugation of SUMO2 to KAT5 in response to DNA damage, facilitating repair of DNA double-strand breaks (DSBs) via homologous recombination (HR) (PubMed : 32832608). Mediates sumoylation of PARP1 in response to PARP1 trapping to chromatin (PubMed : 35013556). Mediates sumoylation of KLF8, repressiing KLF8 transcriptional activity and cell cycle progression into G(1) phase (PubMed : 16617055). Sumoylates ALKBH5 downstream of MAPK8/JNK1 and MAPK9/JNK2 in response to reactive oxygen species (ROS), inhibiting ALKBH5 RNA demethylase activity (PubMed : 34048572).
